This build is used for gaming and video editing. It seems to be able to handle just about anything I throw at it. I may upgrade to an i7 for video rendering in the future.
Many of the parts and peripherals I purchased on sale. The PC came in under $1000 at the time it was built. (If you live near a Microcenter, look for open box and combo deals) The peripherals were all about half price during Cyber Monday.
Edit: This system was built in late 2012-early 2013.
